Somewhat functional javascript namespaces implementation

gistfile1.js

var namespace = function (name) {
    'use strict';

    var self, namespaces, i, max;
    if (name.indexOf('.') >= 0) {
        namespaces = name.split('.');
        self = this;
        for (i = 0, max = namespaces.length; i < max; i += 1) {
            self = namespace.call(self, namespaces[i]);
        }
    } else {
        if (this[name] === undefined) {
            self = function (name) {
                return namespace.call(self, name);
            };
            this[name] = self;
        }
        self = this[name];
    }
    return self;
};

//Examples
namespace('MyApp')('Namespace')('Test1')('Test2');
namespace('MyApp')('OtherNamespace')('Test1')('Test2');
namespace('MyApp.Just.Another.Way.To.Call.It');

//You can create a function in a namespace doing something like this:
namespace('MyApp')('Namespace')('Test1')('Test2').testFunction = function () {
    'use strict';

    console.log('hello!');
};
